This Switch will allow you to network better than ever. This new Linksys rackmount Switch delivers non-blocking, wire speed switching for your 10 and 100 megabit network clients, plus multiple options for connecting to your network backbone. Twenty-four 10/100 ports wire up your workstations, while the two integrated 10/100/1000BaseTX ports connect to other switches and the backbone at Gigabit speeds. And the mini-GBIC ports allow future expansion through alternate transmission media like optical fiber. All the 10/100 ports on this Switch support IEEE 802.3af standard (802.3af) Power-over-Ethernet (PoE) capabilities. Each port can detect connected 802.3af-compliant network devices, such as IP phones or wireless access points, and automatically supply the required DC power. The Switch can provide DC power to a wide range of connected devices, eliminating the need for an additional power source and cutting down on the amount of cables attached to each device. Once configured to supply power, an automatic detection process is initialized by the Switch that is authenticated by a PoE signature from the connected device. Detection and authentication prevent damage to non-PoE devices. The Switch features WebView monitoring and configuration via your web browser, making it easy to manage the 128 VLANs and up to 4 lagging groups. Or if you prefer, you can use the integrated console port to configure the Switch. The non-blocking, wire-speed switching forwards packets as fast as your network can deliver them. All ports have automatic MDI/MDI-X crossover detection. Each port independently and automatically negotiates for best speed and whether to run in half- or full-duplex mode. Head-of-line blocking prevention keeps your highspeed clients from bogging down in lower-speed traffic and fast store-and-forward switching prevents damaged packets from being passed on into the network. Use the instructions in this User Guide to help you connect the Switch, set it up, and configure it to bridge your different networks. These instructions should be all you need to get the most out of the 24-port 10/100 + 2-Port Gigabit Switch with WebView and Power over Ethernet. 1 Chapter 1: Introduction Welcome 24-Port 10/100 + 2-Port Gigabit Switch with Webview and Power over Ethernet What's in this Guide?

A green LED indicates a functional network link through the corresponding port (1 through 26) with an attached device. A blinking LED indicates that the Switch is actively sending or receiving data over that port. A green LED indicates a powered device is connected to the corresponding port (1 through 24). A green LED indicates a link to the corresponding port (Gigabit ports 25 and 26) is operating at 1000Mbps. No light indicates either no link or a link operating at a speed of 10/100Mbps. Link/Act PoE Speed 3 Chapter 2: Getting to Know the Switch The Front Panel 24-Port 10/100 + 2-Port Gigabit Switch with Webview and Power over Ethernet Ports LAN (1-24) The LAN ports connect to Ethernet network devices, such as other switches or routers. Gigabit1 (25)/Gigabit 2 (26) The Switch is equipped with two Gigabit RJ-45 ports that are shared with two mini-GBIC ports. If a Gigabit mini-GBIC port is being used, the associated RJ-45 port cannot be used. They link to high-speed network peripheral system or clients at speeds of up to 1000Mbps. Console The Console port is where you connect a serial cable from a PC's serial port. The Back Panel The power port is located on the back panel. Figure 2-2: Back Panel Power The Power port is where you will connect the power cord. The Side Panel A security slot, where you can attach a lock to protect the Switch, is located on a side panel. Figure 2-3: Side Panel 4 Chapter 2: Getting to Know the Switch The Back Panel 24-Port 10/100 + 2-Port Gigabit Switch with Webview and Power over Ethernet RJ-45 Ports The Switch is equipped with 24 auto-sensing RJ-45 ports. These RJ-45 ports support network speeds of either 10Mbps or 100Mbps, and can operate in half and full-duplex modes. Auto-sensing technology enables each port to automatically detect the speed of the device connected to it (10Mbps or 100Mbps), and adjust its speed and duplex accordingly. The Switch's RJ-45 ports also support the IEEE 802.3af Power-over-Ethernet (PoE) standard that enables DC power to be supplied to attached devices using wires in the connecting twisted-pair cable. Any 802.3afcompliant device attached to a port can directly draw power from the Switch over the twisted-pair cable without requiring its own separate power source. This capability gives network administrators centralized power control for devices such as IP phones and wireless access points, which translates into greater network availability. For each attached 802.3af-compliant device, the Switch automatically senses the load and dynamically supplies the required power. The Switch delivers power to a device using the two data wire pairs in the twisted-pair cable. Each port can provide up to 15.4 W of power at the standard -48 VDC voltage. To connect a device to a port, you will need to use a network cable. You will need to use Category 5 (or better) cable. For more information on twisted-pair cabling, refer to Appendix B: Cabling. The Gigabit Expansion Ports The Switch is equipped with two Gigabit Ethernet ports that have shared mini-GBIC ports, which provide for the installation of one expansion module. These ports provide links to high-speed network segments or individual workstations at speeds of up to 1000Mbps (Gigabit Ethernet). To establish a Gigabit Ethernet connection using a mini-GBIC port, you will need to install an MGBT1, MGBSX2, or MGBLH1 Gigabit expansion module and use Category 5e cabling or fiber optic cabling. For more information on fiber optic cabling, refer Appendix B: Cabling The Console Port The Switch is equipped with a serial port labeled CONSOLE (located on the front of the Switch) that allows you to connect to a computer's serial port (for configuration purposes) using the provided serial cable. You can use HyperTerminal to manage the Switch using the console port. With this and many other Linksys products, your networking options are limitless. Go to the Linksys website at www.linksys.com for more information about products that work with the Switch. 5 Chapter 2: Getting to Know the Switch RJ-45 Ports 24-Port 10/100 + 2-Port Gigabit Switch with Webview and Power over Ethernet Chapter 3: Connecting the Switch Overview This chapter will explain how to connect network devices to the Switch.

Each Gigabit port has a shared mini-Gbic port. If there is a connection to one of the mini-Gbic ports then the corresponding Gigabit RJ-45 port cannot be used. Port Configuration You can use the Port Configuration or screen to enable/disable an interface, set auto-negotiation and the interface capabilities to advertise, or manually fix the speed, duplex mode, and flow control. Enable ­ Allows you to manually enable or disable an interface. You can disable an interface due to abnormal behavior (for example, excessive collisions), and then enable it again, once the problem has been resolved. You may also disable an interface for security reasons. Auto-negotiation (Port Capabilities) ­ Allows auto-negotiation to be enabled/disabled. When auto-negotiation is enabled, you need to specify the capabilities to be advertised. When auto-negotiation is disabled, you can force the settings for speed, mode, and flow control.The following capabilities are supported. · 10half - Supports 10 Mbps half-duplex operation · 10full - Supports 10 Mbps full-duplex operation · 100half - Supports 100 Mbps half-duplex operation · 100full - Supports 100 Mbps full-duplex operation · 1000full (Gigabit only)- Supports 1000 Mbps full-duplex operation (Default: Autonegotiation enabled; Advertised capabilities for 100BASE-TX ­ 10half, 10full, 100half, 100full; 1000BASE-T ­ 10half, 10full, 100half, 100full, 1000full; 1000BASE-SX/LX/LH (SFP) ­ 1000full; 100BASE-FX (SFP) ­ 100full Speed/Duplex.

Figure 4-24: Port Configuration Figure 4-23: Port Status 21 Chapter 4: Configuration using the Console Interface Configuring the Switch through the Console Interface 24-Port 10/100 + 2-Port Gigabit Switch with Webview and Power over Ethernet PoE Configuration The PoE Main Menu screen displays three menu choices: System PoE Configuration, Port PoE Status and Port PoE Configuration. Figure 4-25: PoE Main Menu System PoE Configuration The Power Configuration screen allows you to set the PoE power allocation from the Switch to connected devices. The Switch's power management enables total Switch power and individual port power to be controlled within a configured power budget. Port power can be automatically turned on and off for connected devices, and a perport power priority can be set so that the Switch never exceeds its allocated power budget. When a device is connected to a port, its power requirements are detected by the Switch before power is supplied. If the power required by a device exceeds the power budget of the port or the whole Switch, power is not supplied. Figure 4-26: Power Configuration Port PoE Status The Power Port Status screen allows you to view the current PoE settings for each port on the Switch. Ports can be set to one of three power priority levels, critical, high, or low. To control the power supply within the Switch's budget, ports set at critical or high priority have power enabled in preference to those ports set at low priority. For example, when a device is connected to a port set to critical priority, the Switch supplies the required power, if necessary by dropping power to ports set for a lower priority. If power is dropped to some low-priority ports and later the power demands on the Switch fall back within its budget, the dropped power is automatically restored. Figure 4-27: Power Port Status 22 Chapter 4: Configuration using the Console Interface Configuring the Switch through the Console Interface 24-Port 10/100 + 2-Port Gigabit Switch with Webview and Power over Ethernet Port PoE Configuration The Power Port Configuration screen allows you to set the PoE settings for each port.

Jumbo Frames. Shows if jumbo frames are enabled. This switch provides more efficient throughput for large sequential data transfers by supporting jumbo frames up to 9216 bytes. Compared to standard Ethernet frames that run only up to 1.5 KB, using jumbo frames significantly reduces the per-packet overhead required to process protocol encapsulation fields. To use jumbo frames, both the source and destination end nodes (such as a computer or server) must support this feature. Also, when the connection is operating at full duplex, all switches in the network between the two end nodes must be able to accept the extended frame size. And for half-duplex connections, all devices in the collision domain would need to support jumbo frames. Enabling jumbo frames will limit the maximum threshold for broadcast storm control to 64 packets per second. The current setting for jumbo frames can be displayed with the show system command. Use the drop-down menu to Enable or Disable the transmitting and receiving of Jumbo Frames for this switch. Figure 5-5: Sys.

Maintaining an accurate time on the switch enables the system log to record meaningful dates and times for event entries. If the clock is not set, the switch will only record the time from the factory default set at the last bootup. When the SNTP client is enabled, the switch periodically sends a request for a time update to a configured time server. You can configure up to three time server IP addresses. The switch will attempt to poll each server in the configured sequence. The Time Synchronization screen displays the following information. Figure 5-9: Sys. Info - Time Synchronization Screen SNTP Client. Configures the switch to operate as an SNTP client. This requires at least one time server to be specified in the SNTP Server field. (Default: Disabled) Current Time. Displays the current time. Name. Assign a name for the time setting. Hours. Set the hours for the clock. Minutes. Set the minutes for the clock. Direction. SNTP uses Coordinated Universal Time (or UTC, formerly Greenwich Mean Time, or GMT) based on the time at the Earth's prime meridian, zero degrees longitude. To display a time corresponding to your local time, you must indicate the number of hours and minutes your time zone is east (after) or west (before) of UTC. Click the SNTP Client checkbox to Enable SNTP Client. Uncheck it to disable it. Set the name, hours and minutes using the text fields. Set the Direction by choosing the Before-UTC or After-UTC.

VLANs help to simplify network management by allowing you to move devices to a new VLAN without having to change any physical connections. VLANs can be easily organized to reflect departmental groups (such as Marketing or R&D), usage groups (such as e-mail), or multicast groups (used for multimedia applications such as videoconferencing). The VLAN screen displays the following information for each VLAN and each port. Selected VLAN. Lists all the current VLAN groups created for this system. Up to 128 VLAN groups can be defined. VLAN 1 is the default untagged VLAN. Up Time at Creation. This displays the amount of time since this VLAN was created (that is, System Up Time). Status. Shows if this VLAN is enabled or disabled. VLAN ID. ID of configured VLAN (1-4094, no leading zeroes). VLAN Name. Name of the VLAN (1 to 32 characters). VLAN type. Shows how this VLAN was added to the switch. · Default: The Switch's default VLAN. · Static: Added as a static entry. Member Information. Shows the VLAN interface members. Tagging Information.

Select VLAN membership for each interface by marking the appropriate radio button for a port or LAG: · Tagged. Interface is a member of the VLAN. All packets transmitted by the port will be tagged, that is, carry a tag and therefore carry VLAN or CoS information. · Untagged. Interface is a member of the VLAN. All packets transmitted by the port will be untagged, that is, not carry a tag and therefore not carry VLAN or CoS information. Note that an interface must be assigned to at least one group as an untagged port. · None. Interface is not a member of the VLAN. Packets associated with this VLAN will not be transmitted by the interface. Figure 5-16: Adding/Editing VLAN Screen 37 Chapter 5: Configuring the Switch through the Web Utility Switch Config 24-Port 10/100 + 2-Port Gigabit Switch with Webview and Power over Ethernet VLAN Port You can configure VLAN behavior for specific interfaces, including the default VLAN identifier (PVID), accepted frame types, ingress filtering and mode. VLAN identifier (PVID). VLAN ID assigned to untagged frames received on the interface. (Default: 1) · If an interface is not a member of VLAN 1 and you assign its PVID to this VLAN, the interface will automatically be added to VLAN 1 as an untagged member. For all other VLANs, an interface must first be configured as an untagged member before you can assign its PVID to that group. Accepted frame types. Sets the interface to accept all frame types, including tagged or untagged frames, or only tagged frames. When set to receive all frame types, any received frames that are untagged are assigned to the default VLAN. (Options: All, Tagged; Default: All) Ingress filtering. Determines how to process frames tagged for VLANs for which the ingress port is not a member. (Default: Disabled) · Ingress filtering only affects tagged frames. · If ingress filtering is disabled and a port receives frames tagged for VLANs for which it is not a member, these frames will be flooded to all other ports (except for those VLANs explicitly forbidden on this port). · If ingress filtering is enabled and a port receives frames tagged for VLANs for which it is not a member, these frames will be discarded. · Ingress filtering does not affect VLAN independent BPDU frames, such as GVRP or STP. However, they do affect VLAN dependent BPDU frames, such as GMRP. Mode. Indicates VLAN membership mode for an interface. (Default: General) · Trunk ­ Specifies a port as an end-point for a VLAN trunk. A trunk is a direct link between two switches, so the port transmits tagged frames that identify the source VLAN. Note that frames belonging to the port's default VLAN (that is, associated with the PVID) are also transmitted as tagged frames. · General ­ Specifies a hybrid VLAN interface. The port may transmit tagged or untagged frames. · Access ­ Is the default setting for all ports. Fill in the required settings for each interface, click Submit. 38 Chapter 5: Configuring the Switch through the Web Utility Switch Config Figure 5-17: Switch Config - VLAN Port 24-Port 10/100 + 2-Port Gigabit Switch with Webview and Power over Ethernet LAG Configuration You can create multiple links between devices that work as one virtual, aggregate link.

When set to receive all frame types, any received frames that are untagged are assigned to the default VLAN. (Options: All, Tagged; Default: All) Mode. Indicates VLAN membership mode for an interface. · Trunk ­ Specifies a port as an end-point for a VLAN trunk. A trunk is a direct link between two switches, so the port transmits tagged frames that identify the source VLAN. Note that frames belonging to the port's default VLAN (that is, associated with the PVID) are also transmitted as tagged frames. · General ­ Specifies a hybrid VLAN interface. The port may transmit tagged or untagged frames. · Access ­ Is the default setting for all ports. 40 Chapter 5: Configuring the Switch through the Web Utility Switch Config Figure 5-20: LAG Broadcast Control Screen Figure 5-21: VLAN LAG Configuration Screen 24-Port 10/100 + 2-Port Gigabit Switch with Webview and Power over Ethernet Port Mirroring You can mirror traffic from any source port to a target port for real-time analysis. You can then attach a logic analyzer or RMON probe to the target port and study the traffic crossing the source port in a completely unobtrusive manner. Monitor port speed should match or exceed source port speed, otherwise traffic may be dropped from the monitor port. All mirror sessions have to share the same destination port. When mirroring port traffic, the target port must be included in the same VLAN as the source port. Set the following attributes for port mirroring using the Port Mirroring screen. Mirror Sessions. Displays a list of current mirror sessions. Source Port. The port whose traffic will be monitored. Type. Allows you to select which traffic to mirror to the target port, Rx (receive), or Tx (transmit). Target Port. The port that will mirror the traffic on the source port. Specify the source port, the traffic type to be mirrored, and the target port, then click Add. Figure 5-22: Switch Config - Port Mirroring 41 Chapter 5: Configuring the Switch through the Web Utility Switch Config 24-Port 10/100 + 2-Port Gigabit Switch with Webview and Power over Ethernet LACP Ports can be statically grouped into an aggregate link (i.e., lag) to increase the bandwidth of a network connection or to ensure fault recovery. Or you can use the Link Aggregation Control Protocol (LACP) to automatically negotiate a lag link between this switch and another network device. For static lags, the switches have to comply with the Cisco EtherChannel standard. For dynamic lags, the switches have to comply with LACP. This switch supports up to four lags. For example, a lag consisting of two 1000 Mbps ports can support an aggregate bandwidth of 4 Gbps when operating at full duplex. To avoid creating a loop in the network, be sure you enable LACP before connecting the ports, and also disconnect the ports before disabling LACP. Set Port Actor ­ This menu sets the local side of an aggregate link; that is, the ports on this switch. Set Port Partner ­ This menu sets the remote side of an aggregate link; that is, the ports on the attached device. The command attributes have the same meaning as those used for the port actor. However, configuring LACP settings for the partner only applies to its administrative state, not its operational state, and will only take effect the next time an aggregate link is established with the partner. Set the System Priority, Admin Key, and Port Priority for the Port Actor. You can optionally configure these settings for the Port Partner. (Be aware that these settings only affect the administrative state of the partner, and will not take effect until the next time an aggregate link is formed with this device.) After you have completed setting the port LACP parameters, click submit. To assign ports to the member list, click LACP Membership.
